Unfortunately, the thermal conductivity of the most commonly used insulation materials decreased only fractionally over the last decades. As a result, better building insulation equates to thicker building insulation. Sun, 12 Feb 2017 13:35:00 +0000 There Is More to the Picture Than Meets the Eye For centuries diffraction was believed to set the fundamental limit to optical microscopy, so that structures below about half the wavelength of light cannot be resolved. In the last ten years, however, a variety of approaches has been developed, which enable optical imaging way beyond the classical diffraction limit [1].
